Product description: Tranee

1. What is the product?

Tranee is an intelligent multi-platform language learning space, combining a browser extension (Chrome/Edge Extension) and Web App to help users with instant contextual translation, view bilingual subtitles, and remember vocabulary long-term using spaced repetition (SRS) methods.

2. Problems solved

When reading technical documents or watching foreign videos, learners often face interruptions due to having to switch tabs to look up dictionaries, encounter rigid translations lacking context, and quickly forget new words because there is no seamless review system. Tranee thoroughly addresses this issue by directly integrating an AI translation assistant, native pronunciation, and an intelligent vocabulary notebook into the daily web browsing flow.
